How do I work my Motorola Hitachi DV-P315 features without a remote?

Introduction
The Px4x DVD Upgrade is an advanced modification to your DVD player, which adds extra features and enables you to get more from your machine. The upgrade supplements the DVD player and in no way harms the playback quality or removes any performance features of the DVD player.

Main Features
The DVD Upgrade adds the following features to your DVD player:
 Multiregion capability
 Macrovision disable

Players Supported
The following DVD players are supported by this version of the DVD Upgrade:

 Pioneer DV-340, Pioneer DV-343
 Pioneer DV-444
 Pioneer DV-545

Modification Details
Multiregion selection
Nearly all DVD discs on the market today are encoded with a specific "region" in mind and are made in such a way that a disc designed for "region 1" will not play on a player designed for "region 2". This is so that the Hollywood studios can control the release of titles in different geographical regions all over the world. Our upgrade allows you to select between regions 1 to 6.
Macrovision & CGMS disable
All DVD players have a system called Macrovision built in to the player, which is designed to stop the copying of DVD discs to video. However, this system can have adverse affects on some projectors. For this reason the DVD Upgrade disables Macrovision to solve any problems.

Operating Instructions
You can select the region code by remote. This region will be tried first when playing a disk.
Due to this design, the modification will work on the RCE (Regional Code Enhancement) protected DVD’s. In some cases it will be necessary to insert a conventional (non RCE protected) disc before playing a RCE protected disc. Follow the instructions as detailed bellow:

1. Turn the player on without a disc in it
2. On the remote control, press 'SETUP'
3. Use right arrow to select 'General'
4. Use down arrow to select 'Basic'
5. Press 'ENTER' on the remote control
6. Press 'Display' on the remote control
You should see the region code and OSD version that the player is set to
7. Press 'Condition/Memory'
8. Press '1', '2', '3', '4', '5' or '6' to change the region code of the player
The text will disappear
9. Press ' Display ' on the remote to control the region
10. Press 'SETUP' on the remote to exit. Play the disc
This dident work for me but mayby work for you.
